IPv6 News

A study conducted by RIPE Labs indicates that about 1.89% of spam are received over IPv6. “With the increased deployment of IPv6, we were curious to see how much the amount of spam sent over IPv6 increases. We looked at the e-mail system of the RIPE NCC and produced some statistics that could be seen as an indication for the overall trend of spam sent over IPv6,” says RIPE in a blog post explaining the analysis. Group also notes that the study was based on one week’s worth of data and that it excluded messages already rejected by blacklisting and greylisting.

Broadband ISP Andrews & Arnold (AAISP) has announced that punters using the Santa-Fe coffee shop in Bracknell for free broadband access, will now do so via Internet Protocol Version 6 (IPv6). The announcement is unusual because IPv6 generally isn’t a consumer marketable term, preferring instead to work behind the scenes where nobody can see it.

Network engineers from Yahoo are pitching what they admit is a “really ugly hack” to the Internet’s Domain Name System, but they say it is necessary for the popular Web content provider to support IPv6, the long-anticipated upgrade to the Internet’s main communications protocol.
Yahoo outlined its proposal for changes to DNS recursive name resolvers at [...]

Leading Web content providers — including Google, Yahoo, Netflix and Microsoft — are conducting early-stage conversations about creating a shared list of customers who can access their Web sites via IPv6, the long-anticipated upgrade to the Internet’s main communications protocol.
The DNS Whitelist for IPv6 would be a list of IP addresses that have functioning IPv6 [...]

Popular video sharing site YouTube was inaccessible to users this morning, displaying an ‘Http/1.1 Service Unavailable’ warning instead of the site’s front page. Mirror sites, such as www.youtube.co.uk and www.youtube.com.au, were also closed for business.

Mid March a special plenary session of the Canadian standard committee isacc was convened in Ottawa to review the final report [PDF] of the Canadian IPv6 Task Group. It was unanimously approved and the essence of its 66 pages are seven recommendations for Government, Industry, Service and Content providers, and the regulator, CRTC to proceed with diligence, even some sense of urgency.

One paragraph provides an interesting new twist to the exhaustion debate: Is the Internet already becoming less reliable as a consequence? paragraph 3.1 of the report says:

‘Evidence has shown that most of the remaining IPv4 address space is already in use by organizations. Within the few remaining IPv4 address blocks available as of January 2010, 90% of that address space contains prefixes which have been identified as already in use by some organizations, resulting in decreased reliability. Therefore, the recipients of these prefixes, when allocated, will see unwanted traffic to their networks and many organizations will not be able to reach these recipients’ networks. In other words, the remaining address space will be less reliable to use than the IPv4 address space already in use. As the remaining address space approaches zero, it is likely that people will experience unreachability of sites and networks as well as more instability in IPv4 routing.’

Could we be using dirty prefixes without knowing it? What are the possible consequences? How to make sure we get clean addresses from our ISP? Marc Blanchet’s blog on the topic might provide some beginnings of an answer.

If you consider that the IPv4 address pool has only 24 prefixes (/8’s) left and that 22 of them are dirty, means only two really clean ones are left! The dirtiest neighbourhoods are 1.0.0.0/8, 2.0.0.0/8 and 100.0.0.0/8 , they’re apparently harbouring nests of address squatters.

An IPv4 dirtyness index might be a useful addition to the expiry counters. A healthier alternative however might be to start dipping in the IPv6 reservoir.
